To all whom it may concern:

Be it known that l, FRANK S. BASKIN, acitizen of the United States, and residing at Cleveland Heights, in the county of Cuyahoga and State of Ohio, have invented a new and useful Table Attachment for Seats, of which the following is a specification.

T his invention relates to improvements in table-attachments for seats, and pertains more especially to a table-attachment the table of which is adjustable forwardly and rearwardly and up and down and can be positioned horizontally or at an angle to a horizontal plane.

One object of this invention is to produce a table-attachment of the character indicated which is attractive and simple and durable in construction and avoids interference with the requisite knee-room of the occupant of the seat.

Another object is to facilitate the assemblage of the component parts of said tableattachment and the manipulations required for a readjustment of the table, and to provide improved means for securing the table in the desired adjustment.

lVith these objects in view, and to attain any other object hereinafter appearing, this invention consists in certain features of construction and combinations and relative arrangements of parts, hereinafter described in this specification, pointed out in the claims, and illustrated in the accompanying drawings. r

In said drawings, Figure 1.is a top plan of a table-attachment embodying my invention. Fig. 2 is a vertical section taken along the line 22, Fig. 1, looking forwardly. Fig. 3 is a vertical section taken along the line 33, Fig. 2, looking in the direction indicated by the arrow. Fig. 4 shows a portion of Fig. 3, except that in Fig. 4: the table is inclined whereas in Fig. 3 the table i 'in a horizontal position. Fig. 5 is a horizontal section taken along the line 5-5, Fig. 3, looking downwardly. Fig. 6 is a vertical section taken along the line 6-6, Fig. 3, looking forwardly. Figs. 7 and 8 are vertical sections taken alon the line 7-7 and line 88, respectively, Fig. 6, looking forwardly. Fig. 9 is a horizontal section taken along the line 9-9, Fig. 6, looking downwardly. Portions are broken away in the drawings to reduce their size and to more clearly show the construction.

Application filed December 22, 1919. Serial No. 346,667.

Referring to said drawings, 10 (see Figs. 1, 2 and 3) indicates a substantially vertical standard which is preferably of wood and rendered rigid in any approved manner with the framework of a seat and arranged at the forward end and right-hand side of the seat-proper 12 which is preferably of wood, and said seat-proper has a forward extension 13 to which the standard is secured. The lower portion 14 of said standard is shown in Fi 3 as forming a forwart leg of said seat. aid standard has its upper portion, which is arranged above the seat-proper 12, forming a substantially vertically arranged guideway engaged by a correspondingly arranged metal bracket which is constructed in any approved manner and (see Figs. 3 and 5 has its body formed by a vertical metal plate 15 which is arranged opposite and next the outer side of said standard. Preferably the guidcwayforming upper portion of said standard has its front and rear edges vertical and parallel, and the bracket-body 15 has flanges 16 overlapping said edges. The bracket-body 15 extends above the standard 10 and is provided at its upper end with two forwardly and rearwardly spaced substantially parallel arms 17 which (see Figs. 1, 2 and 3) extend over said standard and laterally of and inwardly from said body and are arranged in one and the same horizontal plane. Each arm 17 is shown tied at a point central between its ends to the adjacent flange 16 by a diagonally arranged bar 18 secured in any approved manner to said flange and to said arm. The hereinbefore mentioned bracket is adjustable vertically, and means employed for securing said bracket in the desired vertical adjustment comprise a clamping plate 20, two bolts 21 and nuts 22. (See Figs. 8 and 5.) The bar 20 is arranged at and transversely of the inner side of the standard 10. The bolts 21 have their heads overlapping the inwardly facing side of the bar 20 and have their shanks extending loosely through said bar and through vertical slots 23 in the standard 10 and loosely through the bracketbody 15, and the nuts 22 are threaded onto said shanks at the outer side of said bar. Obviously manipulation of said nuts to loosen them in relation to the standard 10 renders the bracket free to be readjusted vertically, and said bracket is secured in the desired vertical adjustment by manipu- 7 cent guide-bar.

lating said nuts as required to cause the bracket-body 15 to be. clamped tothe outer side of the standard.

Two forwardly and rearwardly extending laterally opposite parallel guide-bars (see Figs. 1, 2, 3 and 6) are arranged over opposite ends respectively of and mounted on the bracket-arms 17, and preferably each of said guide-bars consists of an angle-bar which has one wing or member 25 thereof projecting Vertically upwardly. Said guidebars have their other wings or members 26 horizontal and projecting toward each other and resting on the bracket-arms l7 and secured to and rendered rigid with said arms in any approved manner. Two outer bars are arranged at the outer side and extend endwise of opposite guide-bars respectively, and preferably each of said outer bars consists of an angle-bar which has one wing or "member .27 thereof projecting vertically downwardly and arranged opposite and next the outer side of the adjacent guide-bar and has its other wing 28 projecting laterally andoutwardly. Mounted on the laterally and outwardly projecting members 28 of said outer bars is the table 29 of my improved table-attachment. Said table is secured to said laterally projecting members of said outer bars in any approved manner, and said outer bars are operatively connected, as will hereinafter appear, with two slidebars which extend and are slidable endwise of and supported from opposite guidebars respectively, and preferably consist re spectively of an angle-bar which has one wing or member 30 thereof arranged opposite and projecting vertically upwardly at the inner side of the vertical member 25 of the adjacent. guide-bar and has its other wing or member 31 horizontal'and resting I on' the horizontal member 26 of said adja- Preferably the horizontal member 26v of each guide-bar has two projecting members 32 which are spaced longitudinally of said guide-bar and extend over and into close proximity to the upper side of the horizontal member 31 of the adjacent slide-bar and are therefore arranged to prevent upward displacement of said slide-bar. A pivotal pin 34 (see Fig. 6) extends from 'within the upper portion of the vertical member 30 of each slide-bar into the upper portion of the vertical member 27 of the adjacent outer bar and pivots said outer bar to said slide-bar; The pins 34: thus pivotally connecting the outer bars to the slide-bars (see Figs. 2,3 and 6) are arranged horizontally and at a right an le to and preferably centrally between the ends of said bars and in line endwise. Each pin 34 is embraced by a collar 35 (see Figs. 6 and 8) which is interposed between the vertical members 27 and 30 of the bars connected together by said pin, and said collar braces apart the pin-surrounding portions of said bars as desired. The vertical member 25 of each'guide-bar has such contour or dimensions that it extends under the collar 35 on the pin 34: forming the pivotal connection between the adjacent outer barand the adjacent slide -bar. The forward portion and rearward portion of each slide-bar (see Figs. 3 and 4:) have respectively a horizontal top edge 36 and an inclined top edge 37 which extends upwardly toward said horizontal edge, and the relative arrangement of the parts is such that the outer bars and the con nected table are arranged to be moved, when free to move, from the horizontal position shown in Fig. 3 into the inclined position shown in Fig. 4, or vice versa, and that the table rests on the horizontal top edges 36 or on the inclined top edges 37 of the slide-bars according as the table is in the horizontal position shown in Fig. 3 or in the inclined position shown in Fig. 4, The outer and pivoted bars are arranged wholly externally of the vertical plane in which the hereinbefore mentioned bracket is arranged and adapted to be moved for readjustment vertically, so that said bracket offers no obstruction to the vertical members of said bars during the actuation of the table from the horizontal position shown in Fig. 3 into the inclined position shown in Fig. t.

Simple and eflicient means whereby the slide-bar atone side of a guide-bar and the outer and pivoted bar atthe opposite side ofsaid guide-bar may be clamped to said guide-bar are provided. As shown in Figs. 8 and 9 the vertical member 25 of each guide-bar has a lateral slot 38 extending horizontally and longitudinally of the bar, and the vertical m'ember 27 of the adjacent and outer pivoted bar has a curved slot 39 registering with the aforesaid slot in said guide-bar and concentric relatively to the axis of said pivoted bar, and the vertical member 30 of the slide-bar adjacent said guide-bar has a lateral bolt-hole L0 which registers with said slot in said guide-bar. A bolt has its shank 41 extending betwee the slideb'ars andthrougl the bolt-holes a in said bars and through the slots 38 in the guide-bars and through the slots 39 in the outer and pivotedbars, and said bolt has its head 42 overlapping the outer side of one of said pivoted or outer bars, and a nut is threaded onto the shank 41' at the outer side of the other of said outer bars. The bolt-shank M is embraced by a clamping tube-l5 which has'its ends forming lateral abutments for and is consequently interposed between the inner sides ofthe vertical members 30 of the slide-bars. Obviously a manipulationfof the nut l3 as required to tighten it against the outerside 'of the vertical member 27 of the adjacent outer and pivoted bar not only results in the clamping of said member of said pivoted bar'and the vertical members of the adjacent guide-bar and slide-bar by and between said. nut and the adjacent end of the clamping tube 415, but in the clamping of the vertical member of the slide-bar at the other end of said tube and the vertical members of the guide-bar and pivoted bar adjacent the last-mentioned slide-bar by and between the last-mentioned end or" said tube and the bolt-head 42. Manipulation of the nut 43 as required to loosen it in relation to the vertical member 27 of the adjacent pivoted bar renders the table free to, be readjusted. The slots 38 in the guide-bars permit forward and rearward'adjustment or the table,

A and the slots 39 in the vertical members 2'? or the pivoted bars extend, in the horizontal position of the table, .far' enough rearwardly of the bolt-shank ll to permit movement of the table from the horizontal position shown in Fig. 8 into the inclined position shown in Fig. 4;. The slide-bars, the pivoted bars, the bolt extending through said bars and the table are all moved together to readjust the table forwardly and rearwardly, and the relative arrangement ofthose members ot my improved table-attachment, which par ticipate' in rendering the table adjustable forwardly and rearwardly and from a horizontal position into an inclined position or vice verse, is such that they are assembled with facility and not liable to get out or" order or become unduly strained during readjustment of thetable. I would here remark however that preferably the slide-bars are reinforced at their ends by tie-harsifi which are secured to said slide-bars in any approved manner and arranged diagonally of and cross each other in the spacebetween the hereinbefore mentioned clamping tube 45 and the table and are riveted together, as at e7, at their. intersection. What I claim is l.
